Definitions
- the present invention relates to a body implantable connector to facilitate the installation of a vascular implant device.
- An external shunt involves the insertion of tubes, such as those made of Teflon, into an artery and an adjacent vein in a limb and providing an external communication or shunt between the tubes, which extend from the body of the patient.
- the shunt between the tubes is required in order to provide flow through the tubes during that period of time that access is not required for blood treatment.
- a blood or clot or thrombus could form as would be the case if the tubes were simply capped creating a static blood volume when the tubes were not in use.
- Dialysis for example, is accomplished by connecting the arterial and venous tubing to a suitable dialysis unit.
- An internal shunt is performed by joining, within a body, openings between an artery and an adjacent vein, thereby forming a fistula.
- One or two needles are then inserted into the fistula in order to achieve communication with the patient's vascular system.
- the patient suffers major discomfort and pain each time the needles are inserted into the fistula.
- the continous intrustion into the fistula causes it to become layered with scar tissue which ultimately prevents further intrusion, thus requiring the formation of another shunt.
- Both the internal and external shunts increase the loading on the patient's heart due to the joining of the artery to a vein having a lower pressure, thereby lowering the artery's pressure, and requiring the heart to attempt to regain the original arterial blood pressure. Further, in many cases, the reduced circulation in the distal portion of the limb wherein the shunt is effected impairs the adequate perfusion of blood.
- a vascular implant device of the type for which the present invention facilitates the installation hereof is, for example, the valved implant device disclosed in issued U.S. Pat. No. 4,164,221, issued Aug. 14, 1979 of which the inventor of this invention was a coinventor and hereby incorporated by reference.
- FIG. 1 is a pictorial view illustrating the present invention.
- FIG. 2 is a cross-sectional view taken about 2--2 of FIG. 1.
- a body implantable connector generally refered to as 1, is shown.
- the connector 1 is adapted to replace a portion of a patient's internal body fluid or solid carrying conduit such as blood vessel 19.
- the connector 1 is connected to the remaining body conduit 19 means of annular suture 21, or the like.
- the connector 1 may be "side to side” wherein, for example, the side of a vein is connected to the side of an artery.
- Connector 1 includes a tubular member 3 having an increased diameter bulbous portion 5.
- a side port 7 is provided at the approximate midpoint of the bulbous portion 5 of the tubular member 3.
- the tubular member 3 preferably includes inlet 9 and outlet 11 of substantially cylindrical cross-section and having a common center line 13.
- the side port 7 is also preferably of cylindrical cross-section, having a centerline 15 which is substantially perpendicular to the common centerline 13 of inlet 9 and outlet 11 of tubular member 3.
- the bulbous portion 5 preferably has a partial elliptical contour, the elliptical contour being truncated at its ends at the point 17 of diameter expansion from the diameter of tubular member 3 to the diameter of the bulbous portion 5.
- the diameter at the midpoint of the bulbous portion 5 is between about one and one-half to two times the diameter of the tubular member 3 prior to the diameter expansion at point 17.
- the major axis of the elliptical bulbous portion 5 be approximately two times the minor axis of the elliptical bulbous portion 5.
- the connector 1 is preferably of unitary construction, being fabricated of a grafting material which is formed, for example, from Dacron, an E. I. duPont de Nemours & Company product of polyester fiber, or "impra graft", a trademarked product made from polytetrafluoroethylene.
- a grafting material which is formed, for example, from Dacron, an E. I. duPont de Nemours & Company product of polyester fiber, or "impra graft", a trademarked product made from polytetrafluoroethylene.
- at least a portion of the grafting material from which connector 1 is made is coated with collagen.
- the side port 7 of connector 1 is adapted to receive therewithin an end portion of a vascular implant device such as that of U.S. Pat. No. 4,164,221, hereby incorporated by reference.
